Application filed January 27, 1917. Serial No. 144,945.

To all whom it may concern:

- Be it known that I, BAYARD T. MERRILL, a citizen of. the UnitedStates, and a resident of Alderton, in the county of Pierce and- Stateof Washington, have invented a certain new and useful Improvement inAuto mobile-Headlights, of which the following is a specification.

My present invention relates generally to headlights, and moreparticularly to automobile headlights, my object being to provide meanswhereby all upwardly directed.

rays may be cut ofl at certain times and thus all glare eliminated inorder to avoid collisions and other accidents ordinarily due to thelight blinding of pedestrians and drivers of other automobiles.

In carrying out my invention I preferably provide means supplemental tothe usual reflecting surface, and axially disposed light source, wherebywhen the latter is extinguished, only those rays which are downwardlydirected will be givenout, so that, while the roadway remainssuficiently lighted, all blinding-glare is eliminated.

lln theaccompanying drawing illustrating the preferred manner in whichmy invention is carried out 'Figure 1 is a front elevation of myimproved headlight, and

Fig. 2 is a vertical section taken therethrou h substantially on line 22of Fig. 1.

Re erring now to these figures, my improvementscontemplate the use of aheadlight which, in so far as its general framework,'as seen at 10, andits axially disposed lamp bulb 11, are concerned, may be of the usualconstruction, the lamp bulb 11 being, however, in accordance with myimprovements the main source of light, reflected outwardly through theusual lens 12, by means of the reflector 13.

In connection with such a construction, my invention contemplates theprovision of a supplemental lamp bulb or light source 14, above the mainlamp bulb 11, together with a shield 15 constituted, as shown, by adepending flanged portion of the casing and extending across the upperforward portion of the headlight, in front of the supplemental lamp bulbor light source 14, so as to obstruct the upper portion of the dirwtrays emanating from the said supplemental lamp bulb.

Furthermore, in accordance with my invention the reflector 13 consistsof a plurality of angularly disposed reflecting surfaces the. directrays of the said supplemental lamp, the upper portion of the dlrect raysbeing obstructed by the shield 15 which effectively conceals the lampbulb or light source 14 from any point in advance of the headlight inline with or; above the plane of the lower edge of the mid shield.

, It is obvious that, in the normal use of the headlight, with the mainlamp bulb 11 lighted, the supplemental lamp bulb may be either lighted,to be thus ready for use when the main lamp is extinguished, or may beextinguished at the time of the use of the main lamp and lightedsimultaneously with thg eilrtinguishment of thelamp bulb 11.

1. A headlight having main and sugple' mental light sources, the latterlocated a ove the former, a casing having an opaque portion normallyconcealingthe said su ple mental light source and cutting ofl allhorizontal' and upwardly extending direct rays therefrom, and reflectingsurfaces within the casing common to said main and said supplementallight sources and arranged to direct all reflected rays from thesupplemental lightsource in a downward direction.

2'. A headlight having main and supplemental light sources, the formerof which is substantially centrally located, a casing having an upwardlyextended upper rear portion in which said supplemental light source islocated above the main source, an opaque shield extending across the uper front por tion of the casing and depending below the horizontal planeof the said supplemental light source normally concealing the suplemental light source and cutting ofl all horizontal and upwardlyextending direct rays thereof, and reflecting-surfaces within the casingcommon to said main and supplemental light sources and arranged todirect all reflected rays from the latter in a downward direction.

3. A headlight having main and supplemental light sources, a casinghavin an upwardly extended upper portlon in w ich said supplementallight source is located above the main source and having a dependingflange forming an opaque shield extending across the upper front portionof the easing normally concealing the supplemental light source andcutting off all horizontal and upwardly extending direct rays there- 10of, and angular reflecting surfaces Within the casing adjacent the mainand supplemental light sources and arranged with respect to thesupplemental light source to direct all reflected rays therefrom in adownward direction.
